How to Use L298N with Arduino (Quick Guide)
- Connect the motor power supply (typically 7V–12V) to the module
- Connect motors to OUT1–OUT4
- Connect IN1–IN4 to Arduino digital pins
- Use ENA and ENB pins for PWM speed control
- Upload Arduino code to control motor direction and speed
This allows you to:
- Control forward and reverse motion
- Adjust motor speed using PWM
- Operate two motors independently
L298N Wiring Diagram (Basic Setup)
- IN1–IN4 → Arduino digital pins
- ENA / ENB → PWM pins
- OUT1–OUT4 → Motors
- 12V → Motor power supply
- GND → Shared ground with Arduino
Important: Always use a common ground between the motor power supply and the controller.
int motor1Pin1 = 8;
int motor1Pin2 = 9;
int enablePin = 10;
void setup() {
pinMode(motor1Pin1, OUTPUT);
pinMode(motor1Pin2, OUTPUT);
pinMode(enablePin, OUTPUT);
}
void loop() {
digitalWrite(motor1Pin1, HIGH);
digitalWrite(motor1Pin2, LOW);
analogWrite(enablePin, 200);
}
Common Use Cases
